Technology

MEMS Technology: MEMS is an emerging technology which uses the tools and techniques that were developed for the Integrated call up industry to build microscopic machines. These machines argon built on standard ti wafers. The real power of this technology is that legion(predicate) machines faeces be built at the same epoch crossways the surface of the wafer, with no assembly required. Since it is a photographic-like process, it is erect as easy to build a million machines on the wafer as it would be to build just one. These tiny machines argon congruous ubiquitous, and are quickly finding their way into a sort of commercial and defense applications. there are some(prenominal) different big categories of MEMS technologies, outlined below: mess Micromachining: mass micromachining is a manufacturing technique which builds mechanical elements by showtime with a silicon wafer, and then etching away undesirable parts, and being left over(p) with useful mechanical dev ices. Typically, the wafer is photo patterned, divergence a contraceptive layer on the parts of the wafer that you unavoidableness to keep. The wafer is then submersed into a liquid etchant, like thousand hydroxide, which eats away some(prenominal) exposed silicon.

This is a relatively simple and inexpensive dissimulation technology, and is well suited for applications which do not require some(prenominal) complexity, and which are price sensitive. Today, to the senior highest degree all ram sensors are built with Bulk Micromachining. Bulk Micromachined blackmail sensors abide some(prenominal) advantages over traditional closet sensors. They cos! t less, are highly reliable, manufacturable, and there is very severe repeatability between devices. all new cars on the market today have several micromachined pressure sensors, typically used to quantity manifold pressure in the engine. The small size and high reliability of micromachined pressure sensors make them ideal for a variety of medical applications as well. Surface Micromachining: While Bulk micromachining creates devices by etching into a wafer,...If you want to get a in full essay, value it on our website: OrderCustomPaper.com
